The selective breeding of animals for meat, skin, egg,
and byproducts is animal husbandry. The
domesticating of farm animals has been practice for generations.
Over the years man has selectively bred livestock to
alter the genetic qualities, temperament, growth, productivity. This was done
primarily to promote desirable animals for various purposes.
A good example of domesticated animals altered for certain
functions are angora rabbits and goats. Cattle are bred for skin, beef, milk
through selective breeding or modification to increase farm yield.
The quality of livestock today has drastically increased
due to consistent breeding programs. Livestock like chicken is another example
of effective selective breeding. You have chicken specialized in egg laying and
those bred for meat.
This has dramatically changed the way farming methodology
is done throughout the world. This has given rise to mega farms using modified
animals and mechanized equipment.
Breeding
Techniques
Breeding programs that have achieved high quality stock
over the years use artificial insemination techniques. The techniques involve
selecting a quality breed and performing an embryo transfer.
This is usually done by an experience farmer, laboratory
technician or veterinary doctor. Improved the animals genetic is the primary
function of breeding programs.
Implanting embryo to surrogate lesser quality fosters
guarantees increased yield of desirable stock. This cuts across farm animals
used for egg production, meat or fiber.
Another important trait achieved is the food conversion
rate of improved high quality livestock. The major downside to selective
breeding is prevalence of complex diseases and loss of genetic diversity.
Standardized
Husbandry Practice
Over the years major players in the industry identify
many unwholesome practices by farmers and breeding programs. Therefore rigorous
standard have been established to ensure good practices and healthier animals.
The framework ensures healthier animals, reduction in
mortality rate and diseases. The practices aids herd optimization proper land
usage including feeding and medication.
Good organization and standardization of practice
includes animal control mechanism, proper staff training and production
planning. Other factors introduced to optimize yield are property organization,
standard animal enclosures and output.
Another important rule governs waste management protocols
and impact on the environment. It also provides standardization associated to battery,
free run, free range or barn habitation.
Environmental
Impact of Animal Husbandry
The impact of animal husbandry to nature depends on the
mode of farming and type of livestock. We see the devastating impact of cash
crops such as rice totally dissipating local fauna.
The same applies to cattle and goat herding on local
wildlife. In India there is constant clash between nomadic farmers and
endangered spices like elephants and tigers.
Other bad effects of livestock on nature are water
depletion including water pollution from pesticides and animal feces.
Other bad impact is habitat destruction, and vast dead
zones of ocean wildlife. Another major challenge due to animal husbandry
practice is species extinction of wildlife, insects and fauna.
Other unwholesome practices have added to the problem such
as introduction of harmful pesticides and indiscriminate bush burning. Other
harmful agents are the use of synthetic fertilizers, mono-culture and
herbicides.
The negative environmental impact continues because of over-fishing and the use of dynamite by local fishermen. The systemic killing of
natural predators for their skin and bones has caused explosion of other
species. Even the dreadful Ebola outbreak was linked to consumption of infected
monkeys.
To sustain our environment we need to review our farming
culture, livestock farming methodology. The growing human population apart from
depleting the ozone layer through chemical emissions is gradually killing the
planet in unwholesome husbandry practices.
Greenhouse effect, methane emissions, migratory patterns,
exploration and industrialization all play a role on climate change. This adds
to the rapid depletion of the ozone layer.
In recent days we have witnessed climatic changes such as
increased rainfall in some areas, desertification, drought and endless freeze.
Although animal husbandry is necessary due to our exploding numbers, better legislatures
and practices are required.
